with EDI and ALE technologies, distributed business processes within an enterprise have the ability to communicate with each other via one-to-one links. Ina small enterprise which has a small number of components, one-to-one communication is the best way to integrate the business processes as it can be achieved with ease. But in cases where a large number of components are involved, this will bring higher complexity and cost of communication and negative impact on the stability of the environment. In this situation, a common communication infrastructure that allows the central management of the information will avoid these complications and bring more flexibility for expanding the business.
